New Revision: 246219
URL: http://svnweb.freebsd.org/changeset/base/246219
Log:
The MSDOSFSMNT_WAITONFAT flag is bogus and broken. It does less than
track the MNT_SYNCHRONOUS flag. It is set to the latter at mount time
but not updated by MNT_UPDATE.
Use MNT_SYNCHRONOUS to decide to write the FAT updates syncrhonously.
